推荐答案
您可以像这样在片段中设置SupportActionbar:
You can setSupportActionbar like this in fragments:
((AppCompatActivity)getActivity()).setSupportActionBar(mToolbar);
您需要为Fragment
的onCreateView
中的tabbar_layout
充气.像这样:
You need to inflate tabbar_layout
in onCreateView
of Fragment
.Like this:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.tabbar_layout, container, false);
//YOUR STUFF
return rootView;
}
